I always get upset when people write unclear lines.
I do a lot of code reviews, and it's taking years to explain how to write code that makes sense. Some are better, some just write, or worse - copy, things that are ambiguous, or are made such by copying them with small changes.
It's very difficult to specify bullet-proof rules for good code. And after every step devs find more ways to fuck it up.
Cause that one is absolute shit, very difficult to maintain, and requires lots of config changes and even replicas can disconnect when something's not 100% ok.
I will take Postgres over any other DB any day of the week.
Cthulhu fhtagn!
